1 Claim.

My invention relates to new and useful improvements in gas burners foruse in the fire boxes of hot air furnaces and kitchen ranges, and anobject thereof is to provide a novel and Simple burner which will burnwith an orange blue flame so as to give substantially completecombustion and practically eliminate or substantially reduce theformation of carbon deposits or collection of soot in the fire boxes offurnaces or ranges and on the burner and give a maximum of heat for thequantity of gas or fuel burned.

Another object of the invention is to provide a burner which can bemanufactured with facility and at relatively low cost, said burnercomprising a few relatively simple parts which can be easily producedand assembled to form the complete burner, including a stand having abase adapted for supporting the burner on a furnace or range grate andhaving an upright standard to which connection is made to a valvedsupply pipe for gas or oil and through which the gas or fuel flows tothe burner proper consisting of a generator or distributor ringcentrally supported on the standard through a diametrical spider feedingthe gas to a pair or plurality of concentric spaced annular burner pipeshaving jet apertures and communicating with each other at a plurality ofpoints for even distribution of the gas or other fuel to the jets toburn with a uniform hot orange blue flame to give very eflicient heat.

'A further object is to provide burner rings with central annularapertured ribs forming seats or shoulders outside and inside thereof forsupporting reticulated or foraminous annular sleeves in closely adjacentspaced concentric relation on opposite sides of the flames issuing fromthe burner apertures so that the flames will impinge upon the sleevesand insure better and more complete combustion by spreading the flamesand more thoroughly combining the gases or hydrocarbons with air oroxygen by creating a draft upwardly between the burner rings and thesleeves drawing air to the flames or jets and causing the same to spreadand heat the sleeves to a red or White heat, thereby giving moreeificient heating efficiency, and also, greater economy in the use ofthe gas or fuel.

The invention consists in certain novel features of construction andcombinations and arrangements of parts involving the'burner, its standand connection for supporting the burner rings upon which the sleevesare arranged, the formation of the rings and manner of supporting thesleeves thereon on opposite sides of the burner jets and a plurality ofoutlets or tubular connections between the burner rings to insureuniform feed of the gas or fuel to the outer ring, and other features ofconstruction and operation as will be hereinafter more fully pointed outand set forth in the appended claim.

In the accompanying drawin s I have illustrated a complete example of aphysical embodiment of my invention in which the parts are combined andarranged in accordance with one mode I have devised for the practicalapplication of the principles of my invention. It will however, beunderstood that changes and alterations are contemplated and may be madein these exemplifying drawings and mechanical structures, within thescope of my claim without departing from the principles of theinvention.

Figure 1 is a vertical di-ametrical sectional view through the gasburner of my invention, and showing the valved inlet pipe and valvedpilot burner for the same.

Figure 2 is a top plan view of the burner.

Figure 3 is a horizontalsection taken at the plane of the section line3-3 of Figure 1.

Figure 4 is a fragmentary vertical section of a modification of theforaminous or reticulated sleeves similar to Figure 1, but in which thesame are of slotted sheet metal instead of wire mesh as in Figure 1.

Figure 5 is a section similar to Figure 3 but on a reduced scale andshowing three gas outlets or tubular connections between the inner andouter burner rings instead of four as seen in Figures 2 and 3.

In order that the general relation and utility of the burner may bebetter understood, it will be seen that the device comprises a standincluding a base I which is relatively large, flat and heavy to givesubstantial support and adapted to rest upon the grate of a hot airfurnace or kitchen range in which the device is used. The base I isadapted to support an upright central standard 2 which may be fitted inthe bore of a hollow boss or socket 3 formed on and extending up fromthe center of the base. The upper end of the standard 2 has a T-fitting4 mounted thereon, the horizontal nipple 5 of which is adapted forconnection to or receive a supply conduit or pipe 6 connected to asupply main for gas used as fuel, and having interposed therein, ashut-off cock or valve to regulate or cutofi the supply. The supply pipe6 leads into the fitting 4 above the upper end of the standard? and ashort vertical or upright pipe 8 is threaded into the upper end of thefitting 4 to mount the burner proper on its upper end, all of said partsbeing of metal.

The burner comprises a casting or otherwise formed pair of annularconcentric rings including inner and outer rings 9 and H] which arehollow to form pipes and connected in spaced relation by a plurality ofradial pipes ll providing communication between the rings, and shown inFigures 1, 2 and 3 as four in number spaced apart 90 degrees from eachother. A diametrical hollow spider or pipe l2 connects the inner ring 9at diametrically opposite points horizontally and is provided with acentral aperture and a surrounding central depending hollow boss or steml3 in which the upper end of the pipe 8 is threaded. Thus, the gaspassing into the fitting 4 from the supply pipe 6, passes upwardly intothe pipe 8 and then into the pipe l2 to pass out through its open endsinto the inner ring 9 and subsequently through the radial connectingpipes I l into the outer ring I0, to insure even distribution of thegasor fuel to the burner pipes. The burner pipes or rings 9 and [9 areformed with central apertured ribs M forming seats or shoulders I 5 atthe inner-and outer sides thereof and having jet burner apertures I6centrally through the ribs at the top equidistantly spaced apartthroughout the entire circumferences of the rings, through which the gasor oil may issue or pass for ignition to form a multiplicity of smallflames or jet-s. While the gas issuing from the burner apertures or jetsmay be ignited in any suitable manner, the burner is preferably providedwith a pilot light or burner shown as an angular tube ll leading fromthe supply pipe ii outwardly or in advance of the shut-off valve or cockI and provided with a pet-cock or control valve I8 so that a smallquantity or volume of gas may pass to the tip 9 of the pilotindependently of the valve 1 and supply to the burner jets or aperturesiii. The pilot tube ll extends upwardly through the annular spacebetween the rings 9 and If] to ignite the gas from the jets, and asusual, is kept lighted with a small flame. An enlargement or stop collar2i) may be provided on the tube 11 below the tip of the pilot and flamethereof to engage or span the rings 9 and at the bottom to keep the tipproperly positioned.

Supported upon the shoulders or seats I5 of the rings 9 and I9, arereticulated or foraminous annular sleeves 21, 22, 23 and 24, the firsttwo being disposed at the outer and inner seats of the ring ID or outerring, and the latter two being disposed at or upon the inner and outerseats or shoulders [5 of the inner ring 8, but all in spaced concentricrelation. The sleeves on the respective ringsv are in closely adjacentrelation so that the flames of the ignited gas issuing from the burnerorifices IE will impinge upon or strike the sleeves in an upwarddirection and insure better and more complete combustion by spreadingthe flames and more thoroughly combining .the gases or hydrocarbons withthe air or oxygen passing or drawn upwardly between the rings andthrough the sleeves from the inner and outer sides thereof, therebycreating a draft upwardly, especially between the rings and causing theflames to spread and heat the sleeves to a red or white heat. This inconnection with the fact that the gas or oil fuel burns with an orangeblue flame, evidences better combustion and gives better heatingefficiency while at the same time eliminating or greatly reducing theformation of soot or carbon to interfere therewith and also result ingreater economy in fuel or gas consumption. It should be noted that theinnermost sleeve 24 is shorter or lower than the other three sleeves 2I, 22 and 23 tending to confine the heat at the top or permit the sameto spread from the sleeve 24 to the sleeve 23 without giving excessiveheat at the center. All of the sleeves are open ended as shown and inFigures 1 and 2 are shown as being formed of wire mesh for the purposesstated.

In the modification shown in Figure 4 of the drawings, the sleeves arerepresented by the same numbers primed, as 21, 22, 23' and 24, andsimilarly related as heretofore described, but formedof sheet metaltubes having annular horizontal or vertical rows of short slots 25through which the air may pass to support combustion and cause theflames and heat to pass therethrough the same as in connection with thewire mesh of the reticulated or foraminous sleeves 2 l Z2, 23 and 24 aspreviously described. The sleeves of Figure "i'also assume a red orwhite heat to give high heating eificiency and prevent the formation ofsoot or carbon deposits due to the burning of the gas or fuel with anorange blue flame somewhat as in connection with a Bunsen burner, as is.well known and is due to the proper proportions and mixture of gas andair or oxygen to support combustion.

In Figure 5 of the drawings, a slight modification of the burnerstructure as to the generator or distributor ring is shown, in whichinstead of using four of the radial pipes l l between and con nectingthe rings 9 and 19, only three are used in equidistant spaced relationgeometrically in somewhat Y-shape. However, it will be noted that inboth forms of the arrangement of the pipes I l, the latter are staggeredwith relation to the ends of the diametrical spider or pipe l2 so thatin both instances, an even or uniform distribution of the gases to therespective rings and burner orifices or jet apertures is insured. Thisis due to the fact that the gas must travel in a tortuous path beforepassing to and issuing from the orifices or apertures of the burner jetsto be ignited in the manner heretofore explained.

From the foregoing, it will be apparent that I have provided a desirablegas burner for the fire boxes of hot air furnaces, kitchen ranges andthe like which may be economically manufactured and readily assembledand connected to the gas supply line or pipe of a house to be readilyand always available when needed for service. By reason of the base, thedevice will be firmly supported on the grate of the furnace or range inany position desired and yet, it may be easily taken apart for cleaningor replacement of any parts that may be needed after long service. Itwill give efficient and maximum heating service and by reason of itsconstruction, will burn with a blue or orange blue flame, therebyreducing the formation of carbon or soot to a minimum. If fuel oil isused, the same will be heated in the rings of the generator ordistributor rings and the oil may be fed under pressure together withair or steam if desired, so as to burn with efficient heating qualitiesonce the same is ignited as by the pilot flame, but gas is preferred.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is :v

In a gas burner, a horizontally disposed base adapted to be supported ona grate, a hollow boss formed integrally with said base, a verticallydisposed upright standard in the boss on said base, a valved gas supplypipe connected to said stand ard, a burner supported on the upper end ofsaid standard and communicating therewith, said burner including aplurality of horizontally disposed concentric hollow annular ringsconnected by a plurality of equi-distantly spaced pipes arranged betweensaid rings on substantially the same horizontal plane therewith, saidrings having annular top ribs with shoulders at the inner and outersides thereof, and said ribs having a plurality of spaced aperturestherethrough for passage of gas jets, and spaced concentric open endedsleeves supported at their lower ends on the shoulders at opposite sidesof the ribs and apertures for impingement of the jet flamesthereagainst, said sleeves having closely spaced openings therein, theopen upper end of the innermost of said sleeves providing unobstructedpassage of air through said end, said innermost sleeve stopping short ofthe upper end of the adjacent sleeve and causing the draft through thecenter thereof to mix with and deflect the gases rising between theinnermost sleeves toward the outermost sleeve.
